50,000 Lines Of Code to Brew a Coffee
summary
Fifty thousand lines of code glue together an iOS Android and Watch app, backend and shop to an actual capsule coffee machine; prototypes range from styrofoam mock to a BeagleBone emulator to the real hardware, and Wi‑Fi provisioning consumes roughly half the effort. Contract tests against fake services, guided manual tests for physical button interactions, and threat‑model workshops drive security decisions; OTA updates use signatures so firmware rollout survives a compromised server, and the first clear‑water coffee is later fixed into a usable product.
